Buried earth-gray cast iron water supply pipes
Thread Content
I would like to ask the experts: Can K9-grade centrifugal ductile iron pipes buried underground be laid parallel beneath roads where heavy vehicles pass? The road is a temporary path built for railway construction.
Overloaded roads are clearly not an option; what about burying them on both sides of the road?
Thank you, teacher. I mainly want to save on the costs associated with using temporary land
Do you still need to use \"ductile iron pipes\" to save money? Using PE water pipes is cheaper.
The pipe diameter is DN700, and the pipeline length is 4 kilometers. Operating pressure: 0.5~0.8 MPa. For the above operating conditions, what pipe materials are available for selection?
PE water supply pipes have appropriate strength and are the cheapest.
